随着良种事业的发展,防治林木种实害虫已成为良种繁殖工作的重要组成部分。目前由于从事种实害虫研究的人员少、力量薄弱,对一些树种的主要种实害虫的种类、分布、危害及其生境了解不多。现根据已掌握的资料,简单介绍一下十一个树种的主要种实害虫及其生境。一、落叶松种实害虫在山西、河北、辽宁、黑龙江及大兴安岭林区的落叶松母树林中,主要害虫是球果花蝇(Lasiomma spp)、种子广肩小蜂(Euytoma laricis Yano)、球果卷叶蛾(Petrova perangustana Snell)、球果螟(Pioryctria sp)和球果瘿蚊(Camptomyia laricis)。其中球果花蝇有五
With the development of improved varieties, the prevention and control of forest pests has become an important part of the breeding of improved varieties. At present, due to the small number of people engaged in the study of species pests and their weak power, little is known about the species, distribution, harms and habitats of the main species of pests of some species. Now based on the available information, a brief introduction to the main species of eleven species of pests and their habitat. First, the larch species Pests in Shanxi, Hebei, Liaoning, Heilongjiang and Daxinganling forest Larix principis and forests, the main pests are Peacock flies (Lasiomma spp), seeds Broad-shouldered wasp (Euytoma laricis Yano), the ball Petrova perangustana Snell, Pioryctria sp and Camptomyia laricis. One of the fruit flies have five
